ios应用内支付

用uniapp开发iOS应用内支付

准备前端代码
- 服务器端处理
- - 如果iOS支付遇到问题实在解决不了，可以联系我帮忙解决，前端后端都可以解决（添加的时候一定要备注咨询iOS支付问题）

准备前端代码

获取支付通道 (uni.getProvider)

uni.getProvider({service: 'payment',success: (res) => {const iapChannel = res.providers.find((channel) => {return (channel.id === 'appleiap')})}
});

通过支付通道获取产品列表 (iapChannel.requestProduct)

	getProduct(productIds) {return new Promise((resolve, reject) => {this._channel.requestProduct(productIds || this._productIds,(res) => {resolve(res);},(err) => {reject(err);});});}

检查是否存在未关闭的订单 (iapChannel.restoreCompletedTransactions, 可选在合适的时机检查)

	async restore() {// 检查上次用户已支付且未关闭的订单，可能出现原因：首次绑卡，网络中断等异常let _this = thistry {// 从苹果服务器检查未关闭的订单，可选根据 username 过滤，和调用支付时透传的值一致const transactions = await this.restoreCompletedTransactions({});if (!transactions.length) {return;}for (const transaction of transactions) {switch (transaction.transactionState) {case IapTransactionState.purchased://这里写上传数据到服务器的代码console.log('成功');_this.finishTransaction(transaction);}break;case IapTransactionState.failed:// 关闭未支付的订单_this.finishTransaction(transaction);break;default:break;}};} catch (e) {uni.showModal({content: e.message,showCancel: false});} finally {}}

请求支付，传递产品信息 (uni.requestPayment)

	requestPayment(orderInfo) {return new Promise((resolve, reject) => {uni.requestPayment({provider: 'appleiap',orderInfo: orderInfo,success: (res) => {resolve(res);},fail: (err) => {reject(err);}});});}
